The mission of JAVYS, a.s. is to safely, reliably and effectively operate and decommission

nuclear facilities (decommissioning of A1 NPP

and V1 NPP), manage radioactive waste and spent

nuclear fuel, with a minimum impact on the environment.

General overview

Essential conditions for successful decommissioningprocess of nuclear facilities includes followinginfrastructures:

Regulatory Framework

Financing Sources

Management of Materials from Decommissioning

Site Operation Services

Personnel Infrastructure

Infrastructure required for Decommissioning

Regulatory Framework

International Agreements

(Main) Slovak legislation:

Act No. 541/2004 Coll., as amended (Atomic Act)

Act No. 24/2006 Coll., as amended (Act on EIA)

Act No. 355/2007 Coll., as amended

(Public Health Act)

Act No. 50/1976 Coll. as amended

(Construction Act)

Infrastructure required for Decommissioning

Financing Infrastructure

Slovak Nuclear Fund (since 1995)

The Bohunice International Decommissioning Support Fund

Council Regulation No. 1368/2013 on Union support for the nuclear decommissioning assistance programmes in Bulgaria and Slovakia

Nuclear Decommissioning Tax

JAVYS’ own resources

Infrastructure required for Decommissioning

Site Operation Services (SOS)Established Site Operation Services (SOS) remained in most part needed fordecommissioning processes. Main SOS are: Heating and cooling systems, water supply, electricity generation and supply Road&rail access with offloading facilities Sewage (non-/radioactive), potable water systems, other piping networks, office

space Support services (catering, public transport, etc.) Non-radioactive machine shops, workshops and general production facilities,

especially with large machinery, stocks of spare parts, consumables Maps, diagrams, drawings (land drains, active and inactive drains, roadways … ) Area protection system Spent Fuel transport and storage Others

Infrastructure required for Decommissioning

Personnel Infrastructure and Project Organisation

Each decommissioner’s organisation structure is specific to:

Country (overal set up of nuclear industry system, state system, politics,…) Factory (size, type of facility, private/public, shareholders’ expectations) History (after accident/incident, stakeholder requirements, general conditions prior

shut down) Company’s scope of activities (operator of one/multiple facilities, single or multiple

type of facilities, profit or non profit) Future strategy and system of work (company’s business plan) International obligations (special international liabilities and regimes, e.g. EU

funding) Human resources available in space and time (knowledge of decommissioning

aspects)

Waste flow depending of limits for release into environment, for materials, limits and conditions for storage in surface storage, acceptance limits and parameters for individual decommissioning technology, radiological parameters updated to the RAW

treatment date or radiological control. Procedures before RAW treatment, selection, low pressure compaction, general waste

disposal, local transport.

Activities generating RAW– decontamination before dismantling, dismantling, civil surface

decontamination, dismantling of contaminated civil parts.
